* The liquid mask didnt stick to the back of the Jackal paint transfer, so after cutting out all the webbing on the outside, I was forced to abandon the idea.
* I cut too hard through the liquid mask, leaving exacto cut marks in the body (seemed I either didnt cut all the way through, or I cut to far, that stuff is really touchy)
* My graphic on the side is a pure display of my non-artistic ability (close up you can see that the line isnt straight) - as well it had some bleeding
* The window tint was very runny, and I put it on too thick, it had run lines on the window (not that big of a deal) but it also collected in all the little "pockets" of the body and bleed through the 1 coat of white, 2 coats of black and 3 coats of purple.
* cutting out the body was rough at best, I tied using the exacto, scissors, etc - scuffed the paint in a few places
I did learn a lot though in the process - which is the key thing

I know what not to do next time. I think I will keep the design much simpler to start out with, and I will definately use lighter coats of paint, and just put more coats on to get the coverage I want. Window Tint is out the "window" and I'll just use black for the window, I dont think I could spray that stuff from a can and have it not run. I may or may not use the liquid mask again, I think part of my problem was I put it on too thick, and there were spots that were still that light blue color and they were spongy like (partly due to the foam brush I used to put it on with). very light coats of the liquid mask will produce better results. I can imagine that with the use of an airbrush it would be much better.
One other problem I'm having after the fact is that it seemd the pain is seperating from the plastic after I crash/flip the truck. Looks like a bunch of air bubbles at all the corners/edges now. I washed the inside with dawn/water and rinsed in hot water, then wiped dry with a towel and then let air dry before I put on the liquid mask - not sure what would cause the paint to not stick. Maybe I touched it with the side of my hand while trimming some of the liquid mask??
Still, going by at 45mph it looks pretty sweet, so I'm happy with it, even though I was hoping for a few other things to come out right.
